IMPROVEMENT] IN FASTENERSI FOR MEETING-RAILS OF SASHES.

The' Schedule referred to in these .Letters Patent and making prt of thename.

Sash-Fasteners and I do hereh r declare the followinr when taken inconnection with theacconipanying drawing and the letters of referencemarked thereon, to he a full, clear, and exact description `of thesaine, and which said drawing constitutes part of this specilica- -tionand represents in- Figure l, a top view;

lfigure 2, a side view;

Figure 3, a rear View; and in Figure 4, a view of the lever, the plateinverted.

This invention relates to an improvement in sashfasteners, particularlythat class in which a flat spring is arranged in the rear of the leverto sustain the 1ever in a locked or unlocked position, the object heiligto construct the plate so that it may he made ornamental upon the uppersurface, and, at the saine. lime, the spring covered. f

In the connnon construction a recess is formed upon the. rear of theplate, under 'which the vspring is arranged, the ila-nge which forms theupper lside' of the said recess extending over the lever, so that thepoint ol' the lever passes over both the plate and flange; hence, incasting such plates, they must he molded on thel edge, and cannot beornai'nente'd on the upper sur'- face.

Myinvention consists in the formation of a recess at the rear of theplate opening from the under side; the said recess used as a seat andmeans of seeming the spring, and the lever pivoted to the upper side ofthe' plate, but extending into the said recess sufficiently to bearagainst the spring arranged therein.

A is the lower plate, which is formed with a recess, a, upon the underside, the said recess extending up into a ledge, d, formed att-he rearedge of the plate, as seen in figs. 2 and 3.

1S, the lever, isfpivoted to the plate A by means of a stud, C,extending through the said lever int-ov the plate. A That partof thelever around the pivot is formed square, as denoted in broken lines,lig. et, and in the recess a a fla-t `spring, b, is placed, denoted insolid black, iig. .4, hearing upon the lever. A recess, f, (see iigs. land 2,) being formed through the ledge open ing into the recess a,permits the spring to bear against the lever and the. lever to be turnedfrom right to left.

By this construction the plate is molded flat-that is, so that the flatsurface may he up or down on the mold-board, as the case may be-and theupper surface may be ornamented lin any desirable manner.

The keeper I) is combined with the lever in the usual manner. i

By this construction, also, the upper side 0f the lever, which isexposed, maybe ornamented, as denoted in tig. 1.

The plate A of a sashastener, to which the lever B is pivoted,constructed with a recess, ai, for the insertion of the spring upon theunder side, to bear against the said level', iu the manner substantiallyas described.
